Overview #
The Cavalier King Charles Spaniel is often described as the perfect companion dog — and it’s hard to argue. Sweet, gentle, and endlessly affectionate, Cavaliers adapt to almost any lifestyle as long as they’re with their people. They are not dogs that can be left alone for long hours; their need for companionship is profound.
But the breed carries a heartbreaking secret: an exceptionally high rate of mitral valve disease that affects nearly every Cavalier eventually. Understanding this before you commit is essential.
History & Origin #
Named for King Charles II of England, who was rarely seen without several spaniels at his side, Cavaliers trace back to the toy spaniels beloved by European nobility. The modern Cavalier was revived in the 1920s when American breeders sought to recreate the longer-nosed spaniels seen in old paintings.
Temperament & Personality #
- Love sponges — they want to be touching you at all times
- True companion dogs — bred for nothing else but being with people
- Gentle and patient — outstanding with children, seniors, cats, and other dogs
- Tail wags constantly — the Cavalier default setting is happy
- Separation anxiety risk — they do NOT do well alone
Health & Lifespan #
Mitral valve disease (MVD) affects over 50% of Cavaliers by age 5 and nearly 100% by age 10. It causes heart failure and is the leading cause of death. Other concerns: syringomyelia (skull malformation causing severe pain), hip dysplasia, patellar luxation, and ear infections.
Care #
Exercise: 30 minutes daily. Walks and play suffice. Grooming: Brushing 2–3x/week. Pay attention to ears — floppy ears trap moisture.
Training** #
Eager to please and easy to train. Positive reinforcement works beautifully. Housebreaking can take patience.
